Substitute Part Grouping Explanation

Substitution eligibility for the MAL215959101E3 is determined by strict equivalence across the following critical parameters:

Capacitance value: 100 µF (exact match required)
Voltage rating: 500 V (exact match required)
Tolerance: ±20% (exact match required)
Package configuration: Radial, Can - Snap-In (exact match required)
Lead spacing: 0.394" (10.00 mm) (exact match required)
Physical dimensions: 0.984" Dia (25.00 mm), Height 1.457" (37.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Polarization: Polar (exact match required)

The identified substitute parts meet all mandatory electrical and mechanical parameters. Variations in ESR, ripple current ratings, lifetime specifications, and operating temperature ranges are secondary considerations that do not disqualify substitution when primary parameters align.

Engineering Selection Recommendations

MAL225969101E3 is the primary direct substitute from the original manufacturer Vishay Beyschlag/Draloric/BC Components. This part maintains active product status and full ROHS3 compliance. The extended operating temperature range (-40°C to 105°C) provides additional thermal margin compared to the obsolete MAL215959101E3. The reduced lifetime specification (3000 hours versus 5000 hours at 105°C) and slightly elevated ESR (1.31 Ω versus 1.11 Ω) are acceptable trade-offs for applications where the original part is no longer available.

LSK101M2H---2535S from SURGE is a parametric equivalent meeting all critical electrical and mechanical specifications. This part maintains the original 5000-hour lifetime rating and identical operating temperature range. The higher ESR value (1.99 Ω) and lower ripple current capacity at low frequency (540 mA @ 120 Hz versus 800 mA @ 120 Hz) may impact performance in ripple-current-sensitive applications. This substitute is suitable for general-purpose applications where ESR and ripple current margins are not critical design constraints.

Frequently Asked Questions (FAQ)

Q: Can MAL225969101E3 be used as a direct replacement for MAL215959101E3?

A: Yes. Both parts share identical capacitance (100 µF), voltage rating (500 V), tolerance (±20%), package configuration (Radial, Can - Snap-In), lead spacing (10.00 mm), and physical dimensions. The MAL225969101E3 is manufactured by the same company and is currently in active production status.

Q: What are the differences between MAL225969101E3 and LSK101M2H---2535S?

A: Both parts meet the core electrical and mechanical requirements. Key differences include manufacturer (Vishay versus SURGE), ESR specification (1.31 Ω versus 1.99 Ω @ rated frequency), lifetime rating (3000 hours versus 5000 hours at 105°C), and ripple current capacity. The choice depends on application-specific requirements for ESR and ripple current performance.

Q: Are all substitute parts physically interchangeable?

A: Yes. All three parts share identical lead spacing (10.00 mm), can diameter (25.00 mm), and seated height (37.00 mm). Physical board layout compatibility is guaranteed across all substitutes.

Q: Do the substitute parts maintain RoHS3 compliance?

A: Yes. Both MAL225969101E3 and LSK101M2H---2535S are ROHS3 compliant, matching the compliance status of the original MAL215959101E3.

Q: Which substitute should be selected for high-ripple-current applications?

A: MAL225969101E3 supports higher ripple current at low frequency (960 mA @ 100 Hz) compared to LSK101M2H---2535S (540 mA @ 120 Hz). For applications requiring maximum ripple current capacity, MAL225969101E3 is the preferred selection.
